My physics professor came in to class one day drunk off his ass. He started describing his adventures doing the mall crawl the night before. Eventually he decided to try and teach, and after several failed attempts to stand up, managed to pull the chalkboard down. His DTs were rattling the board so much he couldn't write. At this point he complained it was too hot and took off his shirt. By this time some prudes had gone to the department head, and he was escorted out before he could take off his pants.
